To all woo m i3 may concern:

Be it known that, 1, Jon): B Srnonn, a citizen of the United States, and a resident of Pass Christinn, in the county of Harrison and State of Mississlppi, have invented a, new and useful Improvement in Vulcan.

of which the following is a specification.

I invention is an improvement in vule-vi-nizers anvl'the invention has for its object to provide a vnicnnizer especially designed for with automobile tires, wherein the vnlcanizer is so arranged that the shoe or easing of the eoinplete tire may be easily inzerteai for nileanizing and removed, and wherein n number of inner tubes may he ennui neonsly voiemiized during the vulcanization oi" the tire.

rhirlher object of the invention is to so "1 support portion of the vnlcanizer that it may he on; s ted to a convenient height for vwrking uprei the tire, and to permit the vuicnnizer to he adjusted for various sizes of tires in the drawings: Figure l is a partial top nian view of re vulcanizr-r; Figs 2 and l e lines 2-53 and l l, re-

l'"" elv, oi Fig. l. each view looking in '5" the arrows adjacent to the line is section on the line 3 1 of Ff in the direction of the arrows edges n; to the line. Fig. 5 is an enlergnd seetir 1 slniwing a tire in place and F 6 n so tionzil view showing an electric in the enihodiinento'f theinvention shown in Figs. l. to 4, suitable siispport is pro vidod consisting of a chambered body 1 and a lisl-:-r-:l.inped lmse which may be secured to a iitnhlo support by means of bolts or ikcs 3. The so wort has :1 vertieni nassa 'e l l n 5, registering with an opening 6 in the floor or other supporting surface for the snpporh and the chamber 7 extends transversely of the body of the base near the upper end thereof, the passage 5 extending through this (:linnihered portion and through the uppoi end of thc support A double rack bar l is nnz-untod to IDOYQ in this passage 5. the rnrk lmr having teeth at opposite sides thereof :is shownn Fig. 2. end the rook hnr movable vertirnllv with espeot to the base l v mean of :1 lever 8. This lever 8 is airenged in the chamber 7, and the lever is Led a lengiwalinaliy extending slot througlfwhivh the rack our 4 extends. The

lever at the slot has oppositely extending journal pins and these pins engage recesses 10 in the chamber walls, thus pivotally connecting the lever to the support. The lever has oppositely arranged pznvls 12. which are pivoted to the lever in the opening and at opposite ends of the openin the said pawls being adapted to engage the teeth of the rack bar. It will be obvious that when the free end of the lever is raised and lowered the pawls will alternately engage the" teeth to lift the rack bar, and the rack bar supports the holding mechanism for the tire and part of the vulcanizing mechanism. A 'nloek 13 is secured to the upper end of the bar, the said her having horizontal flanges 14 at its upper end which abut the under face of the olook and the flanges are secured to the block by means of machine belts or screws 15. l threaded rod or shaft 16 journnled in the block at its lower end the said shaft or rod having a plain portion 1'2, whieh engages a central opening in the hlorlv: and the shaft or rod is rotatably held in the block by means of a screw 18, which passes through a Washer 19 and engages n threaded opening in the lower end of the shaft or rod. The washer is of greater diameter than the opening through the block and the shaft or rod is thus held total: l ly in the hlock. shaft or rod has a hand Wheel 20, secured to its upper end for convenience in rotating the same, and a nut 21 is threaded on to the shaft for vertical movement when the shaft or rod is turned, The block 13 is diskshaped as is also the nut, and the nut has pairs of laterally spaced radial lugs 29, to each pair of which is pivotcd the-lower end of a link 23. Each of the links extends upwardly and outwardly to :1 pivotal connection with a section of a hollow casing 24. Four of the links 23 are provided, and each section of the casing 24 is pivoted to two links. Each of the sections .24 is approxi mntelv semi-circular, and each section is (-urved transversely, and is arranged with its roncave face inwardly. The casing is hollow and the ends of each section are closed, as shown more pzu'tieularly in Fig. 4. Each of the sections 0% the casing 2+ hns two pairs of inwardly extending redial lugs 25, the members of each 'pair being spaced apart to receive between them the adjacent and of the adjacent link A second sectional casing 26 is supported by the soon The 1-2, by means of inclined supporting rods 27. Each of the said rods 27 is connected at its lower end to a ring 27", which encircles the body 1 of the support near the base. Each of the sections of the casing 26 is areshaped longitudinally, being approximately a semi-circle, and each casing is arc-shaped transversely. Each section of the casing 26 is also closed at its ends, and the ends are connected by the mechanism shown more particularly in Fig. 1. The casing 26 very closely resembles the casing 24, being however, of larger size and capacity, of such size and capacity that the casing 24 may fit within the casing 26.

The connection between the sections of the casing 26 above referred to comprises radially extending lugs 28 at the ends of the casing. Each of the lugs 28 is recessed or notched at its outer end as shown more particularly in Fig. 4, and a nut 29 is pivoted within the notch of one lug of each section, while a bearing 30 is pivoted in the notch of the other lug. Thus each section of the casing 26 is provided at one end with a pivotally mounted nut and at the other with a pivotally mounted bearing, and a threaded rod 31 is journaled in each bearing, the threaded portion of the rod passing through the nut at the adjacent end of the other section. Each rod is provided with a hand wheel 32 at the end remote from the bearing for convenience in rotating the'same, and it will be obvious that when the rod is rotated by means of the hand wheel the adjacent ends of the sections will be moved toward or from each other.

A gas heater is connected with the casing 26 and is supported by the said casing. This heater comprises two arc-shaped pipes 33, and each pipe is provided with a series of burners 34:. These burners extend upwardly and inwardly as shown more particularly in Fig. 3, being directed toward the outer under surface of the casing 26; The sections of the heater are connected at one end by a flexible pipe 35, the said pipe being fitted over the adjacent ends of the sections and clamped thereto as indicated at 36, and a valve 37 is interposed in one of the sections adjacent to the said pipe. The opposite end from the pipe 6 of one of the sections is closed by a cap 38, and an inlet pipe 39 is connected with the adjacent end of the other section. A cut off valve 40 is interposed between the. inlet pipe 39 and the adjacent section, and it will be Ob lOHS that when this valve is open and the valve 37 closed, the fuel will be supplied only to the one section of the heater. When the valve 37 is opened however, fuel will be supplied to both sections. A hood 41 is arranged between each section of the heater and the adjacent section of the casing, and each hood is approximately triangular in shape in cross section,

surfaces of the casing 26, thus clampin;

having its apex at the section of the heater and the burners 34 extend through the hood at this point into the hood. The side W?" of the hood diverge, the inner wall being seen to the adjacent section of the casing 25 at its lower edge, while the outer wall ext 3 approximately vertical to a connection the outer wall of the'section, near the cei of the said outer wall.

Each section'of the outer casing is vided on its peripheral surface at 1 intervals with hollow extensions 42, are merely casings having one wall. that is, the wall adjacent to the (33? tion, and, the extensions are fitted the outer face of the casing, the on of each extension forming a fiat 2 shown in Fig. 2. Each section of the i ing 26 has three extensions, near as end, and one near the center. Each sect" is provided with a pair of eyes 43, the casings, the members of each j. arranged on opposite sides of the and a clamping device is connectr each pair of eyes. Each of the said 1 ing devices comprises a plate A. has each end av pivotally mounted Mail? 45, and a hooked link 46 is pivoted bearing lug, the hook of each lini adapted to engage an eye 43 sion. A rod 47 is threaded throw plate 44, and each rod has a hand wt; at its outer end. A clamping plate rotatably connected with the inner each rod, and each of the said pie. adapted to cooperate with the fiat on of the adjacent extension. By 1.

these clamping plates inner tubes ar clamped against the extensions 5 t canized at the same time that a shoe 0 ing is vulcanized between the i 26. The clamping elements support: the plates 44 may be easily detached n by releasing the links 46 from th A safety or relief valve 50 is CGlll'lGxfiUI. each section of the casing 26, and a gage 51 is also provided in connection each section.

In operation, the casing sections. 26 are filled or partially filled with wet and a shoe to be vulcanized is clamped he tween the sections '24 and 26. The secti. a 24 may be moved by moving the nut with respect to the block 13. The sectio 24 may be raised above the sections shown in Fig. 2, and the shoe or casing fitted in the sections 26 of the outer c- The rack bar 4 is then lowered an d sections 24 are in approximate registe. the sections 26 but a little higher. The n; wheel 20 is now turned in a direction to the nut 91 with respect to the block to force the sections 24. against the e shoe or casing between the inner and her. gages 51 and the relief or safety valve 50.

The casing 2b may be expanded or contracted by means of the hand wheels 32 to fit the shoe orcasing upon which they are to be used. The inner casing adjusts itself automatically to the outer casing. This casing :7 forced against the outer casing by men s of the shaft or rod 16.

in 5 the device is shown in position to vol anize an inflated shoe in place on the rim. The shoe 54 as shown. isarranged on the rim :iii. and the inner tube 56 is in place. The shoe is fitted into the outer casing :26 as shown. and the inner casing 24 is arranged just beneath the lower edge of the rim 33:": to support the inflated tire. The ooeretion is precisely the same as in the iiirrangcrncnt shown in Figs. 1 to 4'.

in l ig. 6 an electric heater is shown in coioiection with the outer casing '26, corresponding to the casing 26. This heater is in the 'l'orm of a coil 57 of resistance wire. and this wire is arranged within a hood 3:8 corresponding to the hood 41. The terminals 5 of the coil are passed out through nipples 60 in the hood, an insulating sleeve oi being arranged between the terminal and the nipple. and a binding post 62 is countrted with each terminal. the said bindlug post being insulated from the hood by a insulating washer 63. One of the term nals 64 of a suitable source of electrical M'Wi'gjj clamped to each binding post. The operation with the present construction is precisely the same as in those just described. with the exception that electricity used to heat the vulcanizer instead of gas.

liv I'D.Q{\DS.O'E the. lever 8.. the inner casing m the vulcanizer. may be adjusted to the precise height desired. that is. to a con vcnicnt height to operate upon the tire.

It will be noticed from an inspection of hi 2. that the inner sections are preferably connected to the outer sections, bv means t a flexible pipe 65 or the like. This pipe ivil permit the steam to pass from the outer sections to the inner sections to equalim the heating of the article to be'vulcanixed. and since the pipe is flexible. it will not intern re with the movement of the vulcanizer. It will be understood that in Fig. I; the same connection is preferably proyided. A valve is also provided in the connection (55.
